Well played sir! In that case,
@ConElPueblo was correct. I would not have dared to top a €10,000 bid without actually seeing it. So would have gone to you anyway, and all I would have done is make it more expensive for you. Once again, fortune favored the prepared.
As for your questions: 'relume' means that the luminous material on the markers (radium, tritium or luminova) has been repaired/repainted at some point. Because of the greenish color in the auction pics, some suspected that this was the case. Seeing the new pictures above, I actually believe it is still all original.
If I were you, I would seek out a competent watchmaker who services the movement and maybe replaces the crystal (although if it isn't cracked, the scratches can polish right out), put it on a nice leather strap, and that's about it. Maybe the crown or pushers need to be replaced, but that's generally seen as OK (especially if he gives you the original parts back).
Under no circumstances let him polish the case or change the dial, hands or bezel. Some people would repair the hole in the minute hand (which is simply luminous material that fell out of the hand) with color-matched lume, but personally I'd leave it alone.
Please do not (ever) send it to Omega for a service: they will ruin your watch with new parts. If you live in the Northereast of Belgium, I can recommend Ferrie Schweitzer in Heerlen (The Netherlands). He's not officially certified anymore, but he specialises in vintage omega, has 30+ years of experience working at Omega, and has a huge supply of parts. Perhaps most importantly, he's skilled and understands the value that collectors place on originality.
I might take you up on your offer for a beer someday...and the very least, we'd really love to see before and after pictures of your prize ;-)
